Application Range Of Metal Powder

wallpapers Environment 2020-11-25
Metal powder refers to a group of metal particles with a size of less than 1 mm. Including single metal powder, alloy powder and some refractory compound powder with metallic properties, it is the main raw material of powder metallurgy.
The simple substance of metal is generally silver-white. When the metal is under certain conditions, it is black powder. Most metal powders are black.
Scope of application
Metal powder can be used as a raw material for powder metallurgy products, and it can also be used directly.
Industrial raw materials
The metal powders used in this aspect mainly include iron, tungsten, molybdenum, copper, cobalt, nickel, titanium, tantalum, aluminum, tin, lead and other powders, and the consumption accounts for more than 2/3 of the total output of metal powders.

Direct application
The direct application of metal powder is very extensive. E.g:
①Iron powder for welding rod and flame cutting process.
②Ni-Cr-B-Si, Fe-Cr-B-Si, Co-Cr-W and other alloy powders for spraying, spray welding, fusion welding and nickel-coated aluminum or aluminum oxide, nickel or cobalt-coated tungsten carbide And other coated powder. Used to strengthen the wear resistance, heat resistance and corrosion resistance of the surface of the workpiece.
③Ultra-fine aluminum powder for rocket solid fuel.
④The catalyst uses nickel, iron, and cobalt powder.
⑤ Magnetic powders for clutches, tapes, and copiers, such as iron-based alloy powders.
⑥Iron, nickel, cobalt, manganese, magnesium, aluminum, aluminum-magnesium alloy powders for explosives and fireworks.
⑦ Aluminum, magnesium, iron powder, etc. used for deoxidizers, chemical reagents, metal thermal reducing agents, displacers, etc.
⑧Surface coloring, decoration, paint, paint, aluminum, copper and other powders.
⑨Steel shot and bronze shot blasting for surface processing.
⑩ Iron powder and copper powder for metal electrochemical deposition.
